The book spec for camshaft lift is 0.26". I don't see a spec for  
allowable wear. I'm fairly certain that I have the original camshaft  
(a TR4). My measurements are .002" and .003" wear for lobes 1 and 8.  
Lobes 4 and 6 are .008" and .009" worn. The other 4 are .012" worn  
(0.248" lift).

There's an engine rebuild sometime in the future but for now, how bad  
or not so bad are these measurements? What's the effect on performance?
